Sierra Leone Internal Displacement Updates (IDU): Daily Conflict and Disaster Flows

Sierra Leone conflict and disaster population movement data from the Internal Displacement Monitoring Centre (IDMC). The IDU dataset provides provisional, daily-updated information on new internal displacements ('flows') starting from 2025. Finalized and validated estimates are later published in the annual Global Internal Displacement Database (GIDD).

Use Cases

• Monitor daily displacement flows based on provisional event data mentioned in the description
• Analyze conflict and disaster displacement triggers based on event cause categorization
• Compare provisional daily data with validated annual stock data based on the described two-tier IDU/GIDD system

Strengths

• Updated daily for timely insights
• Covers displacements from both conflict and disaster events
• Sourced from the authoritative Internal Displacement Monitoring Centre (IDMC)
• Available via API for programmatic access

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• Data is provisional and may require preprocessing to avoid double-counting as noted in the description
